Abstract

Der Drehschwingungsdämpfer oder Tilger ist durch eine mit der Drehzahl stetig zunehmende Resonanzfrequenz und Versteifung der Federkennlinien des Gesamtsystems gekennzeichnet. Dies ist dadurch erreicht, daß der segmentierte Schwungmassenring (2) innerhalb eines radial äußeren Tragringes (1) oder Nabenringes angeordnet ist. Durch eine Lagerung der Schwungmassensegmentstücke auf Einzelfedern (3',3'') wird außerdem eine axiale und radiale Schwingfähigkeit des Drehschwingungsdämpfers hergestellt. The torsional vibration damper or absorber is through a the resonance frequency increases continuously with the speed and stiffening of the spring characteristics of the overall system featured. This is achieved in that the segmented flywheel ring (2) within a radial outer support ring (1) or hub ring is arranged. By storing the flywheel segment pieces on Individual springs (3 ', 3' ') also become axial and radial Vibration ability of the torsional vibration damper manufactured.
